Busbar Assembly

Abstract

A busbar assembly includes a first and a second busbar, an intermediate insulating member, an insulation mounting assembly, and a fastener. The busbars are arranged at an interval in a thickness direction of the busbar assembly. First and second through holes are formed in respective ones of the busbars. The intermediate insulating member is arranged between the first busbar and the second busbar. A third through hole is formed in the intermediate insulating member and is aligned with the corresponding through holes in the thickness direction. At least a portion of the insulation mounting assembly is inserted through the aligned first, second, and third through holes to fix the first busbar and the second busbar relative to the intermediate insulating member. The fastener is mounted at least partially within the insulation mounting assembly to fix the insulation mounting assembly, the intermediate insulating member, the first and second busbars.
